Tiffani Faison, the chef-owner of Sweet Cheeks Q and Tiger Mama, has been popping up all over lately. On Monday the “Top Chef’’ finalist was behind the counter at the Pinkberry frozen yogurt shop at the Prudential Center serving up her new signature flavor, Sweet Corn With Blueberry Compote and Brown Sugar Buttermilk Biscuit Crumble (try saying that three times fast). On Aug. 27 Faison will make an appearance at the Wine ConneXtion in North Andover for a complimentary tasting event. From 1 to 5 p.m., you can sample her famed BBQ and biscuits while sipping red wine blends and bourbon. For information, visit www.wineconnextion.com.
